The part of a transistor which is hevaily doped to produce a large number of majority carriers is

Options

A. base
B. emitter
C. collector
D. none of these

Answer

To solve the question about which part of a transistor is heavily doped to produce a large number of majority carriers, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Parts of a Transistor**:
A transistor has three main parts: the emitter (E), the base (B), and the collector (C).

2. **Understand Doping in Transistors**:
Doping refers to the introduction of impurities into a semiconductor to change its electrical properties. Heavily doped regions will have a large number of majority carriers.

3. **Determine the Role of Each Part**:
- **Emitter**: This part is designed to inject carriers into the base. It is heavily doped to ensure a large number of majority carriers.
- **Base**: This part is lightly doped and thin, allowing for the control of the current flow from the emitter to the collector.
- **Collector**: This part is moderately doped and collects the carriers from the base.

4. **Conclusion**:
The part of the transistor that is heavily doped to produce a large number of majority carriers is the **emitter**.

### Final Answer:
The part of a transistor which is heavily doped to produce a large number of majority carriers is the **emitter**.
